The Multiquip EM16169 Thrust Washer is a genuine OEM component designed for hydraulic-driven concrete pump models including the LS300, LS300G, LS300GK, LS300P, LS40, LS40D, LS40TD, LS50TD, LS60TD, LS400, LS500, and LS600 series, as well as the ST-45HRM and ST-70. As a direct OEM replacement, the part is manufactured to the same specifications as the original part, ensuring a correct fit within the pump's drive assembly. Sourcing a genuine Multiquip thrust washer means you are installing a component that matches the original design intent — no guesswork on tolerances or compatibility. DHS Equipment supplies this part direct, so you can get your pump back in service with confidence.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to exact thickness and hardness specifications, ensuring correct axial load distribution within the pump drive assembly.
- Drop-In Fitment — Engineered to seat correctly in the drive train of LS and ST series concrete pump models without additional machining or shimming.
- Broad Concrete Pump Compatibility — Fits LS300, LS400, LS500, LS600, LS40, LS40TD, LS50TD, LS60TD, ST-45HRM, ST-70, and related models.
- Protects Critical Drive Components — A correctly functioning thrust washer absorbs axial forces and prevents metal-to-metal contact; a worn washer accelerates bearing and shaft wear throughout the drive assembly.
- Verified Multiquip Part Number — this part is the exact OEM reference for this application, eliminating the risk of ordering an incompatible substitute.
A thrust washer is a flat, hardened disc positioned within a rotating assembly to manage axial (end-to-end) loads and maintain the correct spacing between moving components. In a hydraulic-driven concrete pump like the LS and ST series, the thrust washer sits within the drive train to absorb the pushing and pulling forces generated during operation, preventing components from grinding against one another. When a thrust washer wears thin or fails, it allows excessive axial movement that can damage shafts, bearings, and housings — leading to more extensive and costly repairs if not addressed promptly.
